The Z homing on a BfB Rapman is insured by an inverted bolt placed at the back of the extruder.
The bolt's head is actioning the Z switch when the bed moves up.
The bed to nozzle distance can be controled by tuning the lenght of that inverted bolt.
But I think it could be made much easier...

I will need something to hold a pen in place of the original extruder if I want to use my Rapman as a pen plotter.
As usual, I'm gonna design that part in Sketchup.

When you print using the support feature with a diferent temp setting for the support, the print head will constantly go to its rest position to change its temperature.
Doing so, it will deposit some stringing on the printed object.
Let's see if we can manage to find a solution for that...

Unless you mounted the PCB fan on its wrong side (which you should better check twice - 99% of the Rapman I've seen have been built with both fans upside-down !), you are probably pissed off having it sucking the dust from your desk !
And I don't even speak about the generated noise.
Let's try to find a solution for that...

The plastic conduits are just laying on my desk if I do nothing.
It's not a big deal but it could be better...

Mounting feet on my Rapman raised it enough to allow for an horizontal filament reel to take place under it. But I will have to take off the diagonal ties base...

In my previous post I've been printing Bogdan's right Y belt holders.
But I didn't find any allready done spare parts to replace the left Y belt holders.
So I decided to design them...

Among the spare parts designed by Bogdan I decide to print the Y belt holder...

The way the bearing blocks are held on the original kit design is not ideal.
Bogdan has designed a set of spare parts to replace the bearing blocks.
So I'm gonna print and use them...

The original Rapman kit corners are very fragile and can't be strongly tighten.
Chylld has designed some replacement corners that really look terrific !
So let's have a try at printing one of them...

Having the Rapman printing spare parts for itself is something some other people have been doing before.
So let's see what the others have done that I could use...

Not only the extruder connector is unprotected.
The PCB itself has all the electronics visible...

The second weak point IMHO is that the Rapman has no good feet.
So let's try to design something better...
